Application March 27, Seri a l l{o., 525,709 5 Claims. (01. 173 259 zMy present invention while capable of a wider range of usefulness is especially intended and peculiarly adapted to solve the well recognized problem of preventing corrosion of battery post terminals and their associated connections.

The terminal posts of wet electric cell batteries,- particularly the positive posts thereof are subject to rapid corrosion by the creepage of chemical about them or by the influence of fumes generated in the chemical or both. Such corrosion commonly results in the freezing of the connector pieces to the terminals. Such corrosion is not only productive of poor electrical connections but makes the connector pieces difiicult to dislodge or remove for purposes of cleaning, inspection, repair andrecharging of batteries.

Prior patentees have endeavored to solve this problem in various ways but without exception, where lubricant has been resorted to, they have either failed to deliver the oil where it was most needed, or departed from the highly desirable construction of the connectors or utilized expensive cumbersome constructions prohibitive in cost and/or requiring the use of unconventionalposts or connectors or both.

An object of the present invention is to maintain those surfaces of the post and'connector which are subject to corrosion continuously covered with a protective oil film.

Another object is to accomplish this result without the need for altering the standard construction of the post or the connector and by the use of an extremely inexpensive, simple, rugged, durable oiling attachment, capable of convenient application to a standard terminal structure without the use of special securing means. 7

The invention may be more fully understood from the following description in connection with I the accompanying drawing, wherein Fig. 1 is a fragmentary perspective view of a battery showing my improved oiling device applied to the terminals thereof;

Fig. 2 is a disassembled perspective view of one of the battery posts and its associated parts;

Fig. 3 is a vertical sectional view through the oiling attachment.

Referring with particularity to drawing, 10 represents a standard battery casing from which project the usual tapered terminal posts 11.

The standard connector piece which is used to couple the cable 12 to the terminal post includes a split collar 13 to encircle the post. A headed clamping screw 14 extending through the apertured lugs 15 which project from the collar sections has associated therewith a nut 16 whereby the collar may be,"tightly clamped ab out the i post, Cast integral withthe collar is the usual socket 17 within which the-endof the cable 12 is soldered or otherwise secured. A As thus far described the construction isentirely conventional the present invention being more particularly concerned with maintaining an oil film upon the contacting surfaces of the post' and collar and upon other surfaces wherecorrosion is apt to take effect. V

With this end in View I provide an open topped lubricant cup 18 having a central discharge opening 19 in its bottom and preferably filled with a wad of steel wool or equivalent material 20 which retards and controls the slow flow of lubricant from the cup. This lubricant incidentally is preferably of about the viscosity of liquid petrolatum.

Disposed eccentrically of the cup and pending therebelow is an integral apertured lug 21 so,

disposed with respect to the cup that when the lug encircles the clamping'screw 14 and is held by the nut 16 the'cup 18 is centered above and closely adjacent the post 11. Thus the oiler is retained in position without the use of special securing means and the oil slowly leaking therefrom creeps between the post and collar preventingthem from being frozen together by corrosion and also tending to lubricate other surfaces where corrosion might occur such for instance as the base of the terminal post and the under face of the collar.

The simplicityof construction and convenience of application of the oiler attachment is obvious.

The construction illustrated is particularly useful as equipment for old batteries but it will of course be understood that it is within the scope of the invention to make the oil cup as a unitary part of the connector if desired.

Itwill thus be seen that there is herein described apparatus in which the several features made without departing from the scope thereof, 5 it is intended that all matter. contained in the above description or shown inth'e accompanying drawing shall be interpreted as illustrativeand not in a limiting sense.

Having thus described my invention, what I 10 claim as new and desire to secure by Letters Patent is:

1. Means for supplying lubricant to the terminal post of a storage battery and between such post and its surrounding cable connector including a lubricant cup for disposition above the end of post, having an aperture therein to permit a passage of lubricant from the cup onto the post and means fixed to the cup and secured and positioned by the connector clamping means to retain said cup in centered position.

2. Anti-corrosion means for use in combina tion with a battery terminal post and a split connector encircling the same and a' tightening screw for the connector, said means including a, lubricant container having a bottom outlet and an apertured extension on saidcontainer adapted to encircle thescrew sodisposed relatively to the container that when the extension encircles and is secured on the screw, the container is fixedly held centered adjacent and above the post and meanson the screw for clamping the extension against the connector. I 1 r 3. As a new article of manufacture, a battery post oiler including a cup having a bottom discharge opening ancl-a lug integral with the cup and adapted for engagement with a connector fixture, said lug being apertured to receive a com nector tightening screw.

4. In combination a battery terminal post, a connector encircling and clamped upon the post, a lubricant container arranged above the post having an aperture therein through which lubricant is delivered upon the top of the post and prevent corrosion at the contacting faces of the post and connector, said connector including a split collar and a screw for tightening the latter,

said lubricant container including an integral apertured lug receiving and clamped by the screw and constituting the sole means to prevent displacement of the container.
